1961 revolt against Portuguese rule of Angola
The strike in Baixa do Cassange, also called Mariano's revolt and Maria's war, was a labor strike that is considered the first political movement that would trigger the Angolan War of Independence exactly one month later and the Portuguese Colonial War over the next three years in the Portuguese overseas provinces. The uprising began on 4 January 1961 in the region of Baixa do Cassanje, district of Malanje, Portuguese Angola. By the following day, the Portuguese authorities had successfully suppressed the revolt. 4 January is now Colonial Martyrs Repression Day, a national holiday in Angola.
